Examples of io.vertx.core.buffer.Buffer.appendByte()

io.vertx.core.buffer.Buffer.appendByte()
Appends the specified {@code byte} to the end of the Buffer. The buffer will expand as necessary to accommodate any bytes written.
Returns a reference to {@code this} so multiple operations can be appended together.
